  1. SCAT, a parameter proposed by Shaar and Tauxe (2013) in an effort to reduce the number of parameters used to quantify a paleointensity estimate; GAP-MAX, the gap factor proposed by Shaar and Tauxe (2013), which is a measure of the average Arai plot point spacing and may not represent extremes of spacing; β, a measure of the relative data scatter around the best-fit line and the ratio of the standard error of the slope to the absolute value of the slope (Coe et al. 1978); the maximum angle of deviation (MAD), the scatter of NRM points about the best-fit line (Kirschvink 1980); the deviation angle (DANG), the angle between the free-floating best-fit direction and the direction between the data center of the mass and the origin of the vector component diagram (Tanaka and Kobayashi 2003; Tauxe and Staudigel 2004); FRAC, NRM fraction used for the best-fit line on an Arai diagram determined entirely by vector difference sum calculation (Shaar and Tauxe 2013); n, the number of the selected samples; H δ %, the value of the coefficient of variation
